Manufactured Misfortune/Day1-Anatomy-Med/Dare something else
You were just about to dare her to streak outside and see how she liked it when something clicked in your head.
"Wait, wait, wait. I just realized that you broke the rules of the dare!"
"Huh?"
Em pushed of the glass and took a half-step towards you, holding her towel securely to her chest.
"I said, you broke the rules of your dare."
"Oh did I? And how's that?"
"The rules of the dare was to face the door, and you very clearly aren't facing it."
Her eyes widened as she realized you had a point.
"B-But you didn't say anything before!" she countered.
"I just streaked the backyard! Of course I didn't think of the finer details at the time!"
Emily opened her mouth to try and argue against you but seemed to think better and stopped.
"So does that mean I owe you another hour?"
You contemplate it for a moment before a plan starts to formulate.
"If you go back to facing the door properly then no, but only if you give up my final dare. And before you object, considering that you just made me go streaking twice and locked me outside I'd say that it's more than fair. What do you say?"
